Notes on care
After the winter season:
X
Raise the vehicle, secure it using jack
stands and remove the wheels; see the
vehicle Operating Instructions.
X
Clean the contact surfaces between the
wheel rim and the wheel hub and lightly
coat them with penetrating wax (Carlo-
fon 3650).
X
Check the wheel rims for corrosion damage
and cracks and replace the wheel rims
where necessary.
X
Fit the wheels and lower the vehicle; see
the vehicle Operating Instructions.
After every off-road use:
X
Check the frame, chassis parts and cab for
damage to the paintwork and to the pro-
tective agents and have any damage recti-
fied immediately.
To remove defects or re-apply dual-layer pro-
tection, please consult a qualified specialist
workshop. It has the necessary specialist
knowledge, tools and qualifications to cor-
rectly carry out the work required on your
vehicle. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose.
Compressed-air dryer
Example: drain plugs
X
Every 3 months, unscrew drain plugs
:
on
the compressed-air reservoirs up to
1

4
turn, until compressed air escapes.
If condensed water is emitted, the granu-
late cartridge must be renewed; see the
vehicle's Operating Instructions.
Gearshift linkage on the transmission
Example: ball sockets
X
U 20: clean and grease ball sockets
:
on
the gearshift linkage of the working gears
and on the planetary gear set.

U 300/400/500: clean and grease ball
sockets
:
on the gearshift linkage of the
working and crawler gears as well as on the

Steering spindle
High-pressure cleaning or spray water may
cause the needle bearing grease on the
centre universal joint of the steering spindle
to be washed out. This causes the steering to
be unresponsive or stick. This can be preven-
ted by protecting the needle bearing using a
protective sleeve.
